| Abstract(in English) | This paper provides the design of an integrity check function, which detects in-process data tampering done by the other processes. The function prevents adversaries from hijacking processes to continuously impersonate a legitimate user and to attempt frauds. For practical applicability, both of two basic designs in this paper allow one to dynamically specify any number of data to be checked, and also to check metadata that are essential for the integrity checking. The lazy-checking method, one of the two designs, can reduce the processing overhead that might be a drawback, by delaying integrity checks until the protected data is actually accessed by the user application. |
